I'm going to be doing it to my Grand Am soon. I already have the parts, all I need is good weather to start doing the project.
Here's what you're going to need.
- A donor car at the JY. It can be an Alero or a Grand Am. They're the same car.
- A metric socket set.
- A torque wrench (some bolts are tightened to 130lbnm
- Rear spindle from donor car. It's easier than piecing it all out.
- Rear brake hoses
- Calipers
- Rotors
- Pads
- Parking/Emergency brake cable
When you go to the Junkyard to get the spindle from a Grand Am/Alero, take the whole thing and make sure the parking brake shoes are in good condition. They cost about as much as the whole spindle set itself.
Take the hubs with you too. DO NOT attempt to take them off. If you do, you will realize that the 4 bolts that hold the hub are a joke. The hub is STUCK onto the spindle. You're better off checking to make sure they're not messed up and taking them with you.
You should also have a backing plate. Take the caliper bracket if you're not buying calipers that come with the bracket.
THESE THINGS YOU BUY NEW
You need to get new rotors and pads for the car. Also some hoses. The hoses on the drums are different from the ones that are used on discs.
You can risk yourself and buy calipers at the junkyard. Just remember that looks can be deceiving.
There are 4 or 5 bolts you have to take off. They are torqued to 133 lbft of torque, so you will need a torque wrench.
2 bolts will be on the strut. That attaches the top of the spindle.
3 bolts hold the spindle to the rear suspension. I forgot where they are but I will take pics of it tomorrow.
The parking brake is a bitch to take off. It's pretty much like taking a throttle cable out in which you take the end of the cable and take it out the hole. Parking brake cables have a tendency to not want to cooperate, so you will need vice grips to hold them in a certain place to get the end of the cable out the hole. The cable that attaches to the hand piece also has pins to prevent the cables that attach to the brakes from coming out. You have to push the pins back out.
After that, the swap is the same as the removal, you're just doing the steps backwards, except if you took the parking brakes off last, you're not doing it first.
